摘要： A cushion module for a patient interface is disclosed. The cushion module comprising a first cavity, a second cavity, a nasal aperture and an oral aperture. The first and second cavities are separated by a cavity wall that enables respiratory gas to flow within the cushion module between the first and second cavities when in use. Additionally, the first cavity is configured to communicate respiratory gas to both the mouth and the nares of a patient via the oral aperture and the nasal aperture respectively. The cushion module comprises an exhaust vent to communicate respiratory gas from within the cushion module to externally of the cushion module and the second cavity is in communication with the exhaust vent. Also disclosed are a cavity wall and a cushion module.

摘要： Systems and methods for non-invasive ventilation are provided. The systems may include a gas source that provides breathing gases to a patient through one or more of a primary flow path (PFP) and a flushing flow path (FFP). The system may include a control assembly configured to open and restrict gas flow through the PFP. When the PFP is open, a significant portion of the gas flows through the PFP while the remaining gas flows through the FFP. When the PFP is restricted, a significant portion of the gas flows through the FFP. Increased flow through the FFP may have a high velocity (especially relative to the flow through the PFP). Gas delivered through the FFP may be used to flush dead space. One or both flow paths may contribute to inspiratory positive airway pressure (IPAP), expiratory positive airway pressure (EPAP), and/or positive end expiratory pressure (PEEP).
